FIELD

The disclosure herein relates to an electrically powered accessoryconfigured to be used with at least one of a vehicle, trailer, and atransport container. More particularly, the disclosure herein relates toan optimized power distribution to electrically powered accessoriesamongst one or more electric supply equipment stations.

BACKGROUND

A transport climate control system is generally used to controlenvironmental condition(s) (e.g., temperature, humidity, air quality,and the like) within a climate controlled space of a transport unit(e.g., a truck, a container (such as a container on a flat car, anintermodal container, etc.), a box car, a semi-tractor, a bus, or othersimilar transport unit). The transport climate control system caninclude, for example, a transport refrigeration system (TRS) and/or aheating, ventilation and air conditioning (HVAC) system. The TRS cancontrol environmental condition(s) within the climate controlled spaceto maintain cargo (e.g., produce, frozen foods, pharmaceuticals, etc.).The HVAC system can control environmental conditions(s) within theclimate controlled space to provide passenger comfort for passengerstravelling in the transport unit. In some transport units, the transportclimate control system can be installed externally (e.g., on a rooftopof the transport unit, on a front wall of the transport unit, etc.).

SUMMARY

The embodiments disclosed herein relate to an electrically poweredaccessory configured to be used with at least one of a vehicle, trailer,and a transport container. More particularly, the embodiments disclosedherein relate to an optimized power distribution to electrically poweredaccessories amongst one or more electric supply equipment stations.

In particular, the embodiments described herein can power and/or chargeone or more electrically powered accessories and at the same timemaintain logistical processes for operating the one or more electricallypowered accessories and maintain dispatch schedules for the one or moreelectrically powered accessories while minimizing costs related to, forexample, power demand rates, etc.

For example, the embodiments described herein can coordinate powerdistribution to one or more electrically powered accessories at a powerdistribution site based on infrastructure data about the powerdistribution site, vehicle/electrically powered accessory data from oneor more electrically powered accessories demanding power from one ormore electrical supply equipment (ESE) stations (e.g., electricalvehicle supply equipment) located at the power distribution site, andexternal data from an external source that can impact power demand fromthe one or more electrically powered accessories. The infrastructuredata, the electrically powered accessory data, and the external data canbe from various inputs and use simulation models and historical data topredict an optimization model for scheduling power distribution to theone or more electrically powered accessories while minimizing overallcost (e.g., power distribution site costs, operational costs of theelectrically powered accessories, etc.) and ensuring that theelectrically powered accessories have sufficient power to operate whileat the power distribution site and/or sufficient charge to operate whenthe electrically powered accessory is dispatched from the powerdistribution site.

In some embodiments, the power distribution site can be modular suchthat power distribution capacity can be increased or decreased asrequired and can be flexible such that the power distribution siteincludes multiple ESE stations that may or may not be capable ofdistributing power at any given time. Also, in some embodiments, thepower distribution site can determine whether a new ESE station has beenadded to or removed from the power distribution site. Accordingly, theembodiment described herein can reduce costs for a power distributionsite by reducing the amount of power distributed at peak power demandrates, can reduce capacity strain on the power distribution site and canenable energy balancing amongst the multiple ESE stations.

When the electrically powered accessories are CCUs, the embodimentsdescribed herein can ensure climate control for each of the CCUs, andoptimize timing for starting, for example, a temperature pull down foreach of the CCUs and/or speed for the temperature pull down for each ofthe CCUs. The embodiments described herein can help ensure successfulclimate control of each of the CCUs and provide particular focus to theCCUs providing climate control to relatively more valuable and/orclimate sensitive cargo.

In one embodiment, a method for optimizing power distribution amongstone or more electrical supply equipment stations at a power distributionsite is provided. The method includes obtaining infrastructure dataabout the power distribution site, obtaining vehicle/electricallypowered accessory data from one or more electrically powered accessoriesand one or more vehicles demanding power from the one or more electricalsupply equipment, and obtaining external data from an external sourcethat can impact power demand from the one or more electrically poweredaccessories. Each of the one or more electrically powered accessories isconfigured to be used with at least one of a vehicle, a trailer, and atransportation container. The method also includes generating anoptimized power distribution schedule based on the infrastructure data,the vehicle/electrically powered accessory data and the external data,and distributing power to the one or more electrically poweredaccessories based on the optimized power distribution schedule.

In another embodiment, a power distribution site for distributing powerto one or more electrically powered accessories is provided. The powerdistribution site includes a power converter stage, a plurality ofelectrical supply equipment stations, a transfer switch matrix, and apower distribution controller. The power converter stage is configuredto convert power received from one or more of a plurality of powersources into a power that is compatible with at least one of the one ormore electrically powered accessories. The plurality of electricalsupply equipment stations distribute power received from the powerconverter stage to at least one of the one or more electrically poweredaccessories. The transfer switch matrix is selectively connected to eachof the plurality of electrical supply equipment stations, wherein thetransfer switch matrix selectively distributes power converted by thepower converter stage to at least one of the one or more electricallypowered accessories.

In some embodiments, the transfer switch matrix 230 caninclude additional switches that may or may not be connected to any ofthe ESE stations 250. Accordingly, the transfer switch matrix 230 can beconfigured to connect the power converter stage 220 to less than all ofthe ESE stations 250. Also, in some embodiments, the number of switchesconnected to each of the circuits 222, 224, 226, 228 can vary based onthe needs of the power distribution site 200.

Each of the ESE stations 250 is configured to distribute power receivedfrom the transfer switch matrix 230 to a vehicle and/or an electricallypowered accessory docked at the particular station 250. As shown in FIG.2, the ESE stations 250 are provided at the loading dock 270 and theparking bays 275. It will be appreciated that each of the ESE stations250 can supply power in the hundreds of kilowatts.

Each of the ESE stations 250 includes a DC charger 252 and an AC charger254 that are configured to connect to a vehicle and/or an electricallypowered accessory. It will be appreciated that in other embodiments, oneor more of the ESE stations 250 may include only one of the DC charger252 and the AC charger 254. In some embodiments, one or more of the DCchargers 252 can be an off-board charger for fast charging. In someembodiments, the ESE stations 250 can communicate with a vehicle and/oran electrically powered accessory.

AC power delivered by the AC charger 254 can be single-phase AC or threephase AC power. DC power delivered by the DC charger 252 can be LowVoltage (LV) DC power (e.g., Class A) and/or High Voltage (HV) DC power(e.g., Class B).

It will be appreciated that the number and types of vehicles 280 and/orelectrically powered accessories 285 parked/docked at the loading dock270 can vary based on the needs of the power distribution site 200. Itwill also be appreciated that the number and types of vehicles 280and/or electrically powered accessories 285 parked/docked at the parkingbays 275 can vary based on the needs of the power distribution site 200.It will also be appreciated that the number of loading docks 270 andparking bays 275 can vary based on the needs of the power distributionsite 200.

The power distribution controller 240 is configured to control the powerinput stage 210 and the transfer switching matrix 230. In particular,the power distribution controller 240 is configured to control each ofthe connections 215 to control which of the power sources 212, 214, 216,218 are providing power to the power distribution site 200 at any giventime. The power distribution controller 240 is also configured tocontrol the switches 233, 235, 237 and 239 to control which of the DCchargers 252 and the AC chargers 254 are supplied power for poweringand/or charging a vehicle and/or electrically powered accessory.

The power distribution controller 240 can communicate with one or moreexternal sources including, for example, a telematics unit of a vehicle,a telematics unit of an electrically powered accessory, a trafficservice, a weather service, etc. In some embodiments, the optional HMI260 can allow an operator to communicate with and/or provideinstructions to the power distribution controller 240. Also, in someembodiments, the power distribution terminal can send notification datavia, for example, a short message service (SMS), email, etc. to one ormore users/operators of the vehicles 280 and/or the electrically poweredaccessories 285.

In some embodiments, the optional HMI 260 can provide a user interfacefor management of the power distribution site 200 (including the powerinput stage 210, the power converter stage 220, and/or the transferswitch matrix 230, etc.). In some embodiments, the optional HMI 260 canprovide wired and/or wireless connections to one or more remotemanagement platforms (for example over the Internet) to manage the powerdistribution site 200 (including the power input stage 210, the powerconverter stage 220, and/or the transfer switch matrix 230, etc.).

The power distribution controller 240 can also be configured tocoordinate distribution of power to one or more electrically poweredaccessories docked at the power distribution site 200. The powerdistribution controller 240 can coordinate power distribution based oninfrastructure data about the power distribution site 200,vehicle/electrically powered accessory data from one or moreelectrically powered accessories demanding power from one or more ESEstations 250, and external data from an external source that can impactpower demand from the one or more electrically powered accessories. Theinfrastructure data, the electrically powered accessory data, and theexternal data can be from various inputs and use simulation models andhistorical data to predict an optimization model for scheduling powerdistribution to the one or more electrically powered accessories whileminimizing overall cost and ensuring that the electrically poweredaccessories have sufficient power to operate while at the powerdistribution site 206 and/or sufficient charge to operate when theelectrically powered accessory is dispatched from the power distributionsite 200. Details of coordinating distribution of power is described infurther detail with respect to FIG. 3.

In some embodiments, the power distribution site 200 can be modular suchthat power distribution capacity can be increased or decreased asrequired and can be flexible such that the power distribution site 200includes the plurality of ESE stations 250 that may or may not becapable of distributing power at any given time based on the switches233, 235, 237, 239. Also, in some embodiments, the power distributioncontroller 240 can determine whether a new ESE station has been added toor removed from the power distribution site 200. For example, as shownin FIG. 2, the parking bay 275 may not have an associated ESE station250. Optionally, a new ESE station 250 n (including an optional DCcharger 252 n and/or an optional AC charger 254 n) can be connected to apreviously unused switch of the transfer switch matrix 230 DC charger252 n. Similarly, one of the plurality of ESE stations 250 can bedisconnected from the transfer switch matrix 230 when desired. The powerdistribution controller 240 can communicate with the transfer switchmatrix 230 to determine when a ESE station is connected and/or removablydisconnected from a switch of the transfer switch matrix 230. Thus, thepower distribution controller 240 can dynamically control the transferswitch matrix 230 and coordinate power distribution at the powerdistribution site 200 amongst the available ESE stations 250accordingly.

Thus, the power distribution controller 240 can reduce costs by reducingthe amount of power distributed at peak power demand rates, can reducecapacity strain on the power distribution site and can enable energybalancing amongst the multiple ESE stations 250.

FIG. 3 illustrates a flowchart of a method 300 for optimizing powerdistribution to one or more vehicles (e.g., the vehicles 280 shown inFIG. 2) and/or one or more electrically powered accessories (e.g., theelectrically powered accessories 285 shown in FIG. 2) at a powerdistribution site (e.g., the power distribution site 200 shown in FIG.2). For illustrative purposes, the one or more electrically poweredaccessories described in the method 300 are CCUs. Thus, the termelectrically powered accessories and CCUs are used interchangeably. Itwill be appreciated that in other embodiments, the method 300 can beused with one or more different types of electrically poweredaccessories. It will also be appreciated that in some embodiments themethod 300 can be a rolling or repetitive process that can plan, forexample, hours ahead, days ahead, etc. It will also be appreciated thatin some embodiments the method 300 can create a model for a plurality oftime intervals and can also optionally aggregate all of the timeinterval models.

The method 300 begins concurrently at 310, 320 and 330. In particular,at 310 a power distribution controller (e.g., the power distributioncontroller 240 shown in FIG. 2) obtains infrastructure data about thepower distribution site. This includes concurrently obtaining fleetmanagement priority data at 312, utility data at 314, loading anddispatching schedule data at 316, and power distribution, charging andstorage infrastructure data at 318. The fleet management priority dataobtained at 312 can be data provided by one or more of the electricallypowered accessories (e.g., via a telematics unit) or via an HMI of thepower distribution site (e.g., the optional HMI 260) indicating whatfactors should be prioritized in using the power distribution site(e.g., dispatch time, minimizing cost of utility power, minimizingenergy consumption, prioritizing climate control for certain CCUs,ensuring that one or more of the vehicles can leave on time,prioritizing full charge or partial charge of a particular vehicle,prioritizing order in which each of the vehicles is charged, minimizingcost to a fleet manager (e.g., fully charging a particular vehicle vs.the particular vehicle leaving on time), etc.). The utility dataobtained at 314 can include, for example, current and future costs ofobtaining utility power from a utility power source (e.g., the utilitypower source 212 shown in FIG. 2) and/or technical limitations of thepower distribution site. The technical limitations can be constraintsand/or boundary conditions of the power distribution site and caninclude, for example, technical limitations of the power source(s)providing power at the power distribution site (e.g., the plurality ofpower sources 212, 214, 216, 218 shown in FIG. 2), a maximum poweramount that can pass through an AC bus from the power source(s) to thevehicle(s), an energy rate, a demand rate, etc. For example, when thepower source(s) includes a generator set and/or a battery storage, atechnical limitation can be that the generator set and/or the batterystorage are only capable of supplying a certain amount of power. Inanother example, a technical limitation can be that when there is a highdemand for power from the power distribution unit, the powerdistribution unit can attempt to discharge power from a battery storage.The loading and dispatching schedule data obtained at 316 can includeinformation regarding when vehicles and/or electrically poweredaccessories are arriving to the power distribution site, when vehiclesand/or electrically powered accessories are set to leave the powerdistribution site, etc. When the power distribution controller obtainsfleet management priority data at 312, obtains utility data at 314, andobtains loading and dispatching schedule data at 316, the method 300proceeds to 340. The power distribution controller can use the loadingand dispatching schedule data obtained at 316 to provide plannedschedule boundary conditions to an optimization model at 350. Plannedschedule boundary conditions can include, for example, times at whicheach of the vehicles are required to be finished charging. Also, thepower distribution controller can use the utility data obtained at 314to provide utility boundary conditions to the optimization model at 350.Utility boundary conditions can include, for example, a capacity of thebattery storage, a maximum charging speed, a maximum power beingprovided by the power distribution site, etc.

The power distribution, charging and storage infrastructure dataobtained at 318 can include power distribution capacity of the powerdistribution site, number and types of power converter elements (e.g.,number of rectifier circuits, DC/DC converter circuits, invertercircuits, and/or AC distribution circuits, etc.), a storage capacity ofa battery storage (e.g., the battery storage 218 shown in FIG. 2) thatcan supply power to the vehicle(s) and/or electrically poweredaccessories, etc. The power distribution, charging and storageinfrastructure data obtained at 318 can provide infrastructure boundaryconditions that are provided to the optimization model at 350.Infrastructure boundary conditions can include, for example, a maximumcapacity of the battery storage at the power distribution site, aminimum capacity of the battery storage at the power distribution site,a maximum capacity of the AC and/or DC chargers of the powerdistribution site, a minimum capacity of the AC and/or DC chargers ofthe power distribution site, the number of AC chargers of the powerdistribution site, the number of DC chargers of the power distributionsite, the number of ESE stations, any further information that can beused to plan for charging and/or precooling multiple vehicles and/orelectrically powered accessories, etc.

At 320, the power distribution controller obtains vehicle/electricallypowered accessory data from one or more vehicles and/or CCUs demandingpower from an ESE station (e.g., the ESE stations 250 shown in FIG. 2)at the power distribution site. This includes concurrently obtainingtrip data at 322, telematics data 324, and/or vehicle/electricallypowered accessory data at 326. The trip data obtained at 322 caninclude, for example, route information for each of the vehicles and/orCCUs, climate control setpoints for each of the CCUs, drop-off stop(s)for each of the vehicles and/or CCUs, etc. The telematics data (obtainedat 324) can be obtained from a telematics unit of the vehicles and/orCCUs. In some embodiments, the telematics data can be current telematicsdata. In some embodiments, the telematics data can be historicaltelematics data. Examples of telematics data can include for example,vehicle status data and/or training data. The vehicle status data caninclude, for example, initial status information regarding the vehiclewhen it is at the power distribution site and ready to be charged (e.g.,current temperature within the climate controlled space, state of chargeof the battery of the vehicle/electrically powered accessory, etc.).Training data can include, for example, a mathematical formula that canforecast energy required for a planned trip of the vehicle. Themathematical formula can use, for example, a size of the climatecontrolled space, an ambient temperature outside of the vehicle, anefficiency of a transport climate controlled unit, an amount of energyrequired by the transport climate controlled unit to compensate for aloss of cooling to the ambient, traffic data, weather data, and anyother current or historic data to determine the amount of power requiredby the vehicle/electrically powered accessory for a trip. In someembodiments, machine learning based on field data and updates based ondata obtained over time can be used to obtain the training data. Thevehicle/electrically powered accessory data obtained at 326 can include,for example, technical data regarding the type of power required foroperating and/or charging the vehicle/electrically powered accessoryincluding. The technical data can include, for example, a size of theclimate controlled space towed by the vehicle, an insulation quality ofthe climate controlled space, an efficiency of the transport climatecontrolled unit providing climate control to the climate controlledspace, a resistance of rolling of the vehicle, and any other data thatcan be factor into predicting energy consumption of thevehicle/electrically powered accessory during the trip, The powerdistribution controller can use the trip data obtained at 322 to providepre-dispatch boundary conditions of the vehicle and/or electricallypowered accessory to the optimization model at 350. The pre-dispatchboundary conditions can include, for example, temperature setpoint dataThe power distribution controller can use the telematics data obtainedat 324 to provide initial status data of the vehicle and/or electricallypowered accessory to the optimization model at 350 and can optionallyprovide training data to a trip energy model at 344. The initial statusdata of the vehicle and/or electrically powered accessory can include,for example, a state of charge of a battery of the vehicle and/orelectrically powered accessory upon arriving at the power distributioncenter, a current temperature within a climate controlled storage spacetowed by the vehicle.

At 330, the power distribution controller obtains external data that maybe relevant to power distribution optimization. This includesconcurrently obtaining weather data at 332 and obtaining traffic data at334. The weather data can be obtained at 332 by the power distributioncontroller via, for example, a weather service via the Internet. Thetraffic data can be obtained at 334 by the power distribution controllervia, for example, a traffic service via the Internet. When the powerdistribution controller obtains the weather data at 332, the trafficdata at 334, the vehicle data at 326 and the trip data at 322, thecombined data is provided to the trip energy model at 344.

At 340, the power distribution controller uses a target function modelto generate one or more target functions at 342. The target functionscan include one or more of optimizing against different targets (e.g.,minimizing delay for charging the vehicle/electrically poweredaccessory, minimizing cost for charging the vehicle/electrically poweredaccessory, minimizing energy consumption of the vehicle/electricallypowered accessory, minimizing wear, for example, on a battery of thevehicle/electrically powered accessory, etc. In some embodiments, thetarget function model can determine a cost for each of the one or moredifferent targets and optimize the model based on the cost for each ofthe one or more targets. The target functions are provided to theoptimization model at 350.

At 344, the power distribution controller uses a trip energy model togenerate an energy prediction per trip at 346 for each of the vehiclesand/or electrically powered accessories based on the vehicle data, thetrip data, the weather data, and the traffic data. In some embodiments,the power distribution controller can input the training data obtainedfrom the telematics data at 324 into the trip energy model at 344 togenerate the energy prediction per trip at 346. That is, the trip energymodel determines an estimated amount of power required for a vehicleand/or electrically powered accessory during a specified trip. Theenergy prediction per trip provides a battery state of charge requiredfor the vehicle and/or electrically powered accessory at the start of atrip in order for the vehicle and/or electrically powered accessory havesufficient power to complete the trip. The battery state of chargerequired for the vehicle and/or electrically powered accessory at thestart of a trip is then provided to the optimization model at 350.

At 350, the power distribution controller inputs the target functionsobtained at 342, the utility boundary conditions obtained from theutility data at 314, the planned schedule boundary conditions obtainedfrom the loading and dispatching schedule data at 316, the requiredbattery state of charge at the start of a trip obtained from the energyprediction per trip determined at 346, the pre-dispatch boundaryconditions obtained from the trip data at 322, the initial status dataobtained from the telematics data at 324, and the infrastructureboundary conditions obtained from the power distribution, charging andstorage infrastructure data at 318 into the optimization model togenerate a power distribution schedule for each of the vehicles and/orelectrically powered accessories at 355.

In some embodiments, the power distribution schedule can determine wheneach of the vehicles and/or electrically powered accessories can chargetheir respective rechargeable energy storage and/or start operationwhile parked/docked at the power distribution site. When theelectrically powered accessory is a CCU, the power distribution schedulecan determine when the CCU can use power from the power distributionsite to charge its rechargeable energy storage, when the CCU can beginprecooling climate control while at the power distribution site, andwhen the CCU can use power from the power distribution site to maintainclimate control while parked/docked at the power distribution site. Themethod 300 then proceeds concurrently to 360 and 365.

At 360, the power distribution controller executes the powerdistribution schedule determined at 355 by controlling one or more of apower input stage (e.g., the power input stage 210 shown in FIG. 2), apower converter stage (e.g., the power converter stage 220 shown in FIG.2), a transfer switch matrix (e.g., the transfer switch matrix 230 shownin FIG. 2). Accordingly, the power distribution controller can controlwhen and how each of the vehicles and/or electrically poweredaccessories are provided power from the power distribution site. Thisallows the power distribution controller to power and/or charge one ormore electrically powered accessories and at the same time maintainlogistical processes for operating the one or more electrically poweredaccessories and maintain dispatch schedules for the one or moreelectrically powered accessories while minimizing costs related to, forexample, power demand rates, etc. It will be appreciated that in someembodiments, the power distribution schedule may not schedule for arechargeable energy storage of a vehicle or electrically poweredaccessory to be charged to a complete state of charge. Rather, theoptimization module can distribute sufficient power to the rechargeableenergy storage for an upcoming trip.

At 365, the power distribution controller can provide feedback to auser/operator of at least one of the vehicles and/or electricallypowered accessories regarding the power distribution schedule for theparticular vehicle and/or electrically powered accessory. In someembodiments, the feedback can include a notification when power is beingdistributed to the particular vehicle and/or electrically poweredaccessory, when sufficient power is provided to the vehicle and/orelectrically powered accessory to successfully start and complete atrip, and/or when the power distribution controller determines thatthere may be an alert or failure to provide sufficient power for thevehicle and/or electrically powered accessory to successfully start andcomplete a trip. In some embodiments, the feedback can also include anotification of a delay, for example, in charging the particular vehicleand/or electrically powered accessory to achieve the desired and/orrequired state of charge.
